I would like to talk about two topics. First is a study to examine sea ice floe size and other characteristics from March to June in the Beaufort Sea of the Arctic Ocean. Using MODIS band-1 visible satellite imagery, we tried to estimate floe size, kurtosis, and skewness of sea ice in the Beaufort sea during April-June 2020. The results of both analyses clearly indicate that before melting progressed, the sea ice began to break up, becoming smaller in size and rounder in shape. These findings contribute to our understanding of the mechanisms driving sea ice loss and may aid in the development of sea ice forecasting models. Second, I would like to introduce Japan’s new research icebreaker, Arctic Research Vessel (ARV) Mirai II. JAMSTEC is now constructing ARV Mirai II and she will be delivered to JAMSTEC in November 2026. She will be operated as an “international research platform”, playing a leading role in international projects. I would like to talk about progress of the construction and our activities toward establishing ARV Mirai II as international research platform.
